HA Y-LOA-DER.

Sp ecification of Letters Patent.

Patented Oct. 13, 1908.

To all whom it may concern:

Be itknown that I, JosErH DAIN, a citizen of the United States, residing at Ottumwa, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements; in Hay-Loaders, of which the following a specification, reference being bad to the accompanying drawings;

My invention relates to hay-loaders, and particularly. to loaders of the type illustrated and described in my pending application, Serial Number 299,130, filed February 2, 1906, in which the raking devices are operated by means of 'pitmen connected with cranks, the axes of which are coincident, or substantially so, with the wheel axle. In

Y such hay-loaders there is an elevator frame,

over whichthe hay is elevated by means of reciprocating rakes which are alternately moved upward anddownward by means of the pitmen above referred to,the latter being suspended, or otherwise suitably mounted, so as to. rock as well as reciprocate.

My present improvements, as above stated, are designed particularly. for use in connectionwith loaders of the construction above referred to, but their use is not restricted to such loaders, and they" may be applied to any other construction to which they areadapted;

. In thev accompanying drawings, which illustrate such parts of the loader as are necessary to a clear understanding of my improvements,

Figure 1 is a plan view, partly in'section, illustrating one of the wheels, the axle, one of the cranks, and the adjacent parts; Fig. 2 is a side view, partly in section, taken on line 2-2 of Fig-1; Fig. 3 is an enlarged sectional View taken on line 3-3 of Fi 2; Fig. 4 is a detail in perspective, showing the collar which carries the pawl; Fig. 5-is a detail, showing the manner of securingthe cranks upon the outer ends of the axle; Fig. 6 is a partial side elevation, illustrating my improved loader; and Figs. 7 and 8 are detail views similar to Figs. 1 and.3, showing a modified arrangement of some of the parts.

Referring to the drawings,6indicates the axle, wh1ch 1s squared, or otherwise made non-circular in c'ross-sectiomand is either tu bular or solid, as preferred.

7 indicates pne of the carrying wheelsof the loader, two of-which are provided, as

. usual.

8 indicates one of'ithe cranks, of which there are two, 0 are each end of the. axle 6.

9 indicates 'on e ofthe uprights or standards which support the elevator frame.

It will be pnderstood that the parts at each end of, the axle are duplicates of those at the other .end} so that a description of the parts at one end of the axle will apply equally well to those at he other end thereof.

. As best s own in Figs. 1 and 3, the crank 8, which is louble, as shown at 1011 in Fig. 1, is provided with a sleeve 12 which fits upon the squared axle'fi. Said sleeve is split at its outer and inner ends, as shown in Figs. 3 and 5, the intermediate portion thereof, however, being continuous. The object of so splitting the sleeve 12 is to ,10: vide for securing it tightly upon theazgie 6, which is accomplished at the outer ei'id'jof the axle by a bolt 13 which passes through lugs 1415,, as shown in Figs. *1 and 5, and at its inner end by a bolt 16 which passes through the split inner portion of the inner ends of the sleeve and also through the axle, I

7, which is provided with a hub 17 having an extension 18 at its outer side, as shown in Fig. 3, so as to provide a more extended bearing. surface and to hold the wheel in its proper position. The hub 17 is provided with a suitable ratchet 19, which is engaged by a pawl 20 carried'by a collar 21, which is secured to the bolt 15, having lugs 22 for that purpose, as shown in Fig. 4 and. by dotted lines in Fig. 3. If desired, the ratchet may be carried by the collar 21 and the pawl by the wheel, but I prefer the construction shown.

Asis best shown in Fig. 3, the standard ,or upright 9. is mounted upon the sleeve 12 adjacent to the hub extension 1S,a bear ing-plate or washer 23 being provided between them ito take the wear. The hub extension 18 thus serves to keep the wheel and sleeve 12 serves as a bearing for the standard 9, which may readily be removed or replacedwhen necessary, and provides a very firm and elficient construction.

24 indicates one of the side bars by which the wheel frame is connected with the elevator frame,said side bars being. secured to the standards 9 by angle-braces 25 26, as shown in Figs. 1 and 2.

2728 indicate the pitmen by which the rakes are operated'frorn the cranks 10-11.

29 indicates one of the tongue-irons or draft-bars which are connected to the uprights 9, as shown in Figs. 1 and 2.

In Figs. 7 and 8 I have illustrated a modified arrangement of some of the parts, the sidebars 24 and standards 9 being placed inside the wheels instead of outside, as shown .in Fig. 1, the pawl 20 and hub extension 18 being also reversed, as shown in Figs. 7 and 8 in which the corresponding parts are indicated by corresponding prime numbers. The operation of the parts is substantially the same.

It will be understood that the axle .6, which may be either solid or tubular, and the cranks secured at the ends thereof, together compose a crank-shaft composed of only three pieces. It will also be observed that the wheels are mounted directly upon the sleeves orextensions of the cranks, so that the power is applied directly to the ranks. This provides a very ellicient construction, since, for example, when all the power fondriving the cranks is obtained from one wheel, as when turning a corner, the crank on the side developing the power encompasses the axle for such a distance that-the axle is at no point subjected to any great strains in transmitting the power to the crank on the opposite side. Furthermore, the weight of the machine is carried on those portions of the cranks which extend through the Wheels, so that the weight is distributed overquite a large portion of the axle. A further advantage of my preferred construction, illustrated principally in Fi s.

1, 2 and 3, is that the draft is applied to tie machine between the wheels and the cranks, since the draft-irons 29 are connected to the uprights 9, as shown and described.
